A reference-letter used to designate a given part is employed to indicate such part throughout the several figures of the drawings wherever the same appears.

A is the base of the machine, and a a are side and end walls, tirmlysecured to base A, forming, together with such base, the frame of the machine.

B B are wings to the frame ofthe machine, rigidly secured to the frontend of such frame and forming the means of connecting to the framethe tool-carriages C C, respectively.

D D are movable tool-post heads, mounted on carriages C C, respectively.

E E are wings rigidly secured to base A, on which wings, respectively, one end of the respective carriages C C rests and to which such carriages are respectively arranged to be rigidly secured by an ordinary fastening-as, say, bolt c, Fig. Z-upon and after their proper adjustment.

F is a frame forming part of the frame of the machine, in which are rotatably mounted the several shafts whereby feed motion to the boring-bar of the machine is obtained.

G is the boring-bar, rotatably mounted in the spindle 1I. Rotatablc spindle II extends longitudinally through the frame of the machine in which it is mounted, and at the end thereof adjacent to the tool-carriages C C screw-threads I I are placed thereon, fitting into corresponding screw-threads in a chuck, face-plate, or other equivalent device for securing thereto the pulley or other thing to be bored or turned, or bored and turned, on the machine. g

J J are,journal-bearings of the spindle II in the frame of the machine.

K is a flange on spindle II, against which a chuck or face-plate abuts when in position on the spindle.

L is a flange on the rear or back end of spindle II, and M is a gear-wheel, the hub m, whereof tits over the end of such spindle H, (and over the flange L on the spindle,) and also over boring-bar G, so as to turn loosely thereon, (but fitting reasonably close thereto.)

N is a feather or spline extending into hub m and into a groove in boring-bar (l, so that rotation of such wheel M produces corresponding rotation of the boring-bartl. Longitudinal movement'. of the boringbar in hub m, as well as in spindle II, is thus provided for.

O is a cone-pulley over which the drivingbelt actuating the machine extends. Concpulley O is rigidly secured to shaft P. Shaft P is rotatably mounted in the frame of the machine in bearings Q Q.

To rotate the boring-bar G in either direction, I provide gear-wheel R, secured on so as to rotate with shaft I), gear-wheels S T en gaging with gear-wheel R and gear-wheel U engaging with gear T. Gears S, T, and U are rotatably mounted on frame V, actuated (or the position thereof controlled) by the handle W, so that such gear-wheels S, T, and U may be alternately engaged with gear-wheel M, hereinbcfore described. The rotation of gearwheel M rotates boring-bar G by the interposed feather or spline N. The direction of rotation of such gear-wheel Mis of course determined by the one ofthe gear-wheels S and U in engagement therewith. The longitudinal movement of the boring-bar G, either to feed the boring-bar to or to withd raw it from work, is effected by the following-described mechanism.

A' is arod secured in frame F and in the frame of the machine formed by parts a ct.

l' E is a combined cone-pulley and gearwheel rotatably mounted on rod A', such rod forming a shaft or axle therefor.

C is a cone-pulley on hub m of gear-wheel M, and D' is a belt extending over cone-pulley C' and part B of the combined cone-pulley and gear-wheel B E', such belt being the driving-belt of the mechanisms moving the boring-bar longitudinally.

F is a gear-wheel engaging with gear-wheel E. Gear-wheel F is mounted on rotatable shaft G', so as to produce, when rotated, corresponding rotation thereof.

I J are gear-wheels rotatably mounted to engage with gear-wheel II'.

K' is a rotatably-mounted gear-wheel cngaging with gear-wheel J. lVhcels I and K are mounted on frame R, controlled by handle S, so as to be alternately in engagement with gear-wheel M. The one of the gearwheels I i in engagement with gear-wheel M is determined by the position of the handle S and frame R'. The direction of rotation of gear-whcelM is determined by the one of the gear-wheels I K' in engagement therewith.

N is the rotatable shaft on which wheel M is mounted, such shaft and wheel rotating in unison.

O O are screw-threads on shaft N', engaging with corresponding screw-threads in the traveler I".

Q is a sleeve secured on boring-bar G by bolt T. Sleeve Q' is adjustable on the boring-bar G after loosening the bolt T', and is im movable thereon when such bolt T is tightened against the boring-bar. Sleeve Q and traveler I are connected so as to move longitudinallyin unison, as illustrated in Fig. 6.

A gear (orinterposed gears) between wheels or cone-pulleys C and I3' may be used in place of the belt l), if preferred; but I prefer to use the belt, as in such case the belt will be thrown off by an obstruction which would break the teeth of gear-wheels.

geargear- IIO 583,010 Y re To rotate the spindle H at varying speeds, I have constructed the following-described mechanisms:

Shaft P is hollow a portion of its length, and rod or bar A2, secured at one end thereof to handle B2, is inserted therein, with pins C2 D2 extending through such rod A2 and through slots E2 F2, respectively, in shaft P into engagement with gear-wheels G2 H2, respectively, so as to move such gear-wheels longitudinally on the shaft P, but not so as to affect in any way the rotation of such shaft P or the gear-wheels G2H2 in unison with such shaft. Handle B2 is pivotally secured to the frame of the machine by pin or bolt h2, eX- tending therethrough and through the lug h2, and such handle is secured to the rod A2, so as not to prevent the rotation of the rod, but to produce longitudinal movement therein, as by making groove h4 in collar b2 on the rod and extending the handle around the rod, with a pin extending in the groove, as at b2.

I2 is a sleeve rotatably mounted on spindle H. v

J2 is a gear-wheel on sleeve l2, secured to the sleeve to rotate therewith, and K2is an additionalAgear-wheel on such sleeve,;also secured thereto to rotate therewith. Sleeve I2 turns on the spindle H freely,and when handle B2 is in the positionY illustrated in Fig. G of'v the drawings gear-wheel G2 on shaft P is in engagement with gear-wheel J 2, thereby(when shaft P is rotated) producing rotation of gearwheel J2, sleeve l2, and-gear-wheel K2.

L2 (see Fig. l) is a gear-wheel rotatably mounted Von the shaft M2. Shaft M2 is eccentrically mounted on part N2 of the frame of the machine, so that when the handle O2 is moved into the position thereof illustrated in Fig. l such gear-wheel L2 is in engagement with gear-wheel K2.

P2 is a gear-wheel or a gear-pinion, also mounted on the shaft M2 and secured to gearwheel L2 to rotate in unisontherewith.

Q2 is a gear-wheel mounted on spindle H to rotate in unison therewith. Gear-wheel P2 is thrown into engagement with and out of engagement with gear-wheel. Q2 by the movement of the eccentric shaft M2 when handle O2 is turned. The gear-wheel H2 on shaft P is thrown into and out of en gagement.

with gear-wheel Q2 by the movement of handle B2. When such handle B2 is in the position thereof illustrated in Figs. l and 6, gear wheel H2 is out of engagement with gear-wheel Q2. When handle O2 is in the position thereof illustrated in Figs. l and 2, gear-wheel L2 is in engagement with gear-wheel K2 and gear wheel or pinion P2 is in engagement with gearwheel Handles B2 and O2 beingin the position illustrated in Figs.'l l, 2, and G,rotation of shaft P produces rotation of gear-wheel J2, sleeve l2, and gear-wheels K2, L2, P2, and Q2. Gear-wheel Q2 is secured to the spindle H in the ordinary way, as by a feather or spline, so that the rotation of gear-wheel Q2 will produce corresponding rotation of the spindle. Vhen the gitudinally thereon.

gear-wheel G2 is out of engagement with gearwheel J2 by the placing of handle B2 in proper relative position therefor and gear-wheel H2 is forced into engagement with the gear-wheel Q2, the rotation of such gear-wheel Q2 and corresponding rotation of spindle H is at a greater or faster rate of speed than when the several parts are in the position illustrated -in the drawings-that is, with gear-wheel G2 in engagement with gear-wheel J2.

To obtain the automatic movement of the tool-post head D on carriage C, I have constru cted the following-described mechanisms:

A2 A2 are rotatably-mounted screws in the carriages C C,respectively, extending through the tool-post heads D D, respectively, and iittinginto corresponding screw-threads in such tool-post heads.

B2 B2, Figs. l and 2, are crank-shafts by which the screw-shafts A2 A2 are rotated by hand when desired.

C2 C2 are beveled gear wheels secured tightly on shafts A2 A2, respectively. D2 D2 are beveled gear-wheels secured tightly on vertical shafts E2 E2 to engage with beveled gear-wheels C2 C2, respectively, and F2 F2 are beveledA gear-wheels secured tightly on the lower end of the vertical shafts E2 E2, respectively, to en gage with the beveled gear-wheels H2 H2 and l2 I2, which are loosely mounted on shaft G2.

J2 (see Fig. 4) is a sleeve mounted on shaft G2 to rotate therewith and also to move lon- K2 is a fork fitting into a groove on sleeve J2 (see Fig. 4) and secured by connection L2 to handle M2. Handle M2 turns on pivotal point (or on fulcrum) m2.

N2 is an extension to handle M2, and n2 is a rod secured at one end to the extension N2 and at the other end mov-ably mounted in guide n4. The turning on the pivot m2 of the handle M2 will move the rod n2 longitudinally, and the movement of the rod longitudinally will turn the hand-le M2 on the fulcrum thereof, thereby throwing sleeve J 2 into engagement with one or the other of the gear-wheels 12H2, thereby turning vertical shaft E2 in one or the other direction.

a5 is a stop on the rod n2, placed in the path of the arm d2, (see Figs. 2 and 4,) so that as the arm d2 (such arm being secured on the tool-post head D) is moved to the right and to the left itwill engage with the arm N2 of handle M2 and stop n2 of rod n2 and so turn the handle on its pivot. The engagementA of the arm d2, as last aforedescribed, shifting the sleeve J2, as stated, changes the direction of movement of the tool-post head. Rotation of the shaft G2 in the operation of the machine is obtained by the beveled wheel N2 engaging with beveled wheel O2 on shaft Q2, cone-pulley V2, tightly secured on such shaft Q2, hub R2, loosely mounted on shaft Q2, with gear-wheels on such hub, one of such gearwheels q2 en gagn g with gear-wheel Q2,where by it is rotated,`and the other of such gearwheels S2 engaging with and turning gear- IIO wheel T3, and such wheel Tsrotatably mounted on shaftif3 and secured to rotate with concpulley U3, also on such shaft t3, and the belt W3 connecting cone-pulleys V3 and U3.

The tool-post carriages C C are adjusted relative to the spindle II and boring-bar G by means of screw-threaded shaft A in wing or extension B of the frame of the machine (see Fig. 2) passing through the carriages and fit-ting into corresponding screw-threads in such carriage. The end of the screwthreaded rod or shaft A*t is squared to permit a wrench being placed thereon to turn the same. As the carriages C C are moved to and from the longitudinal center of the machine the sleeves J 3 J 3 slide on the shaft G3, such shaft being grooved and the shaft and sleeves having feathers or splines g3 litting therein. The sleeves J3 J3 therefore rotate with the shaft G3, although movable longit-udinally thereon.

In turning the face of a pulley, wheel, or

other thing 011 the machine where it isde-V signed to have such face convex the carriages- C C are lnovedout of a position at right angles to the wing B and then bolted (by bolts e) in place. rlhe manner in which the carriages C C are secured to the Wings B, respectively, is well illustrated in Fig. 3 of the drawings.

B4 is a groove in wing B, and C4 a tongue from the carriage C, fitting into such groove.

The fit of the tongue C4 in groove B4 permitsall the movement required in the carriage C out of a right angle to the wing B to properly set-such carriage. After the carriages C C are set they are respectively bolted in place to wings E E, respectively. In turning the convex face of the pulley or other thing it is designed that the cutting-tool on one toolpost base shall cut on one side of the center line of the pulley and the other cutting-tool on the other side thereof. One of such tools will of course be set below the center of the boring-bar and the other above such center.

The operation last described will not pro-A combination of a spindle j ournaled in a fram e,-
